The Most Useful Site in the World

Jobs: one form, several tools, the numbers carried forward

A single tool answers a single question. These 8 jobs answer the one you actually had — and every step is a normal tool on this site, opened with your numbers already in it.

How a job works

  1. Open the first step and fill in what it asks.
  2. The rail above the tool shows where you are. Press Next step — it reads the answer you just got and puts it into the next tool.
  3. Everything travels in the web address: tool.html?card=…&field=value&run=1. Nothing is stored, nothing is uploaded, and every step can be shared as a link on its own.

Hand-built, not scraped: each job is checked against the 21 tools it uses on every build, so a renamed field fails the build instead of shipping a link that fills in nothing.

1. Can I afford this home?

Start with what you earn and what you have saved, end with the monthly payment and what overpaying would save.

  1. What a lender might offer Your income, deposit, term and the rate you expect. The result is a borrowing range, not a promise. carries Deposit available into mortgage-down, Rate you expect to pay into mortgage-rate, Mortgage term into mortgage-years
  2. The monthly payment The deposit, rate and term you just used are already in — add the price you are looking at. carries Interest Rate into mo-rate, Term Length into mo-term
  3. What overpaying saves Your rate and term carried over. Add the balance you would still owe.

Honest limits

A job carries numbers you typed, and figures a tool has already worked out — it never guesses. Where a step needs something no earlier step produced (a mortgage balance, a pattern repeat, the time on your recipe card), the step says so and you type it.

Nothing about a job runs without you: no card is executed in the background, and the site cannot see which job you opened. Started a job and stopped? Just reopen any step — the URL keeps that step's numbers.
